Description

Mixed flow pump with self-cleaning structure Technical Field The utility model relates to the technical field of mixed flow pumps, in particular to a mixed flow pump with a self-cleaning structure. Background The mixed flow pump is a pump between the centrifugal pump and the axial flow pump, the specific rotation speed is higher than that of the centrifugal pump and lower than that of the axial flow pump, generally between 300 and 500, and the lift is higher than that of the axial flow pump, but the flow is smaller than that of the axial flow pump and is larger than that of the centrifugal pump. However, the prior art has the following problems: The mixed flow pump in the prior art is mostly lack of a self-cleaning structure, needs to rely on manual frequent disassembly and cleaning, consumes a great amount of labor and time cost, is easy to influence the operation efficiency of the pump due to accumulation of dirt and impurities, shortens the service life, and is difficult to install and disassemble due to the fact that the connecting structure is mainly fixedly connected or complex and non-detachable design, is low in efficiency, and is unfavorable for timely removing faults and replacing components. In view of the above problems, the inventors have proposed a mixed flow pump having a self-cleaning structure for solving the above problems. Disclosure of utility model The utility model aims to solve the problem that a self-cleaning structure and a connecting structure lack of fixed connection or complex non-detachable design, and provides a mixed flow pump with the self-cleaning structure. In order to solve the technical problems, the mixed flow pump with the self-cleaning structure comprises a main elbow, an output end is arranged on the upper side of the main elbow, a connecting end is arranged on one side of the main elbow, an access end is arranged on one side of the connecting end, a cleaning pump is fixedly arranged on one side of the main elbow, a connecting disc is fixedly arranged on the outer side of the cleaning pump, a transmission pipe is arranged on the inner side of the cleaning pump, a spraying shaft is fixedly arranged at the end part of the transmission pipe, and water spraying grooves are symmetrically formed in the outer surface of the spraying shaft. Preferably, the inboard of access end is fixed and is equipped with the connecting pipe, and the inboard of connecting pipe is fixed and is equipped with the installation tube, can dismantle between installation tube and the connecting end and be connected, common screw thread through connection has the screw thread post between installation tube and the connecting end, and the equal thread bush in both ends of screw thread post is equipped with fixation nut, the screw thread post is equipped with sixteen, and sixteen screw thread posts are annular distribution. Preferably, the connecting end is connected with the main elbow through bolt matching, reinforcing blocks are symmetrically and fixedly arranged on the outer surfaces of the connecting end and the main elbow, the corresponding two reinforcing blocks are connected through bolt matching, and a sealing gasket is arranged between the connecting end and the main elbow. Compared with the prior art, the utility model has the beneficial effects that: 1. The self-cleaning of the mixed flow pump is realized by arranging the cleaning pump, the transmission pipe, the spraying shaft and the water spraying groove. The manual disassembly and cleaning workload and frequency are reduced, the maintenance cost is reduced, the service efficiency of the mixed flow pump is improved, meanwhile, dirt and impurities can be effectively prevented from accumulating in the pump, and the service life of the pump is prolonged. 2. According to the utility model, the detachable connection mode of the threaded column and the fixing nut is adopted between the access end and the connection end, so that the installation, the disassembly and the maintenance are convenient, when the pump is in fault or parts need to be replaced, the relevant parts can be quickly disassembled, and the maintenance efficiency is improved.
